Our Read
Aquasana’s conditioner has the longest rated life here and the clearest water-chemistry limits. It also has the narrowest hardness range. Aquasana sells it as an add-on to its Rhino filter for $1,548, or alone for $1,758.Bottom line: A good fit for moderately hard city water that you’re also filtering. At 15 gpg and up, look elsewhere.
